Refund Radar
Read full descriptionHide full description
The money is still yours. It's just that nobody is watching it right now. A return window that closes quietly. A refund that never arrives. A trial month that turns into a yearly contract. The same side wins every time — and it isn't you. Refund Radar keeps an eye on the deadlines and speaks up before it's too late. HOW IT WORKS • Add it: merchant, amount, purchase date. The app suggests the return window. • Get reminded: in time, by notification and email, with the lead time you choose. • Get it back: a template letter is ready, and the refund stays visible until the money lands. WHAT YOU KEEP IN VIEW • Return deadlines for everything you ordered • Open refunds, until they're actually credited • Subscriptions and contracts, before they quietly renew • Warranties, with the matching receipt beside them • Your savings balance: what you clawed back, in black and white WITH PRO • Connect a mailbox — Gmail, Outlook or via forwarding. Orders are recognised automatically. • Photograph a receipt and the entry writes itself: merchant, amount and return window are read out. • Family access for the household. PRIVACY Servers in the EU, GDPR-compliant. No ads, no tracking, nothing passed to third parties. Mailbox access can be revoked at any time, and Refund Radar only looks at what appears to be an order. The app speaks English and German. You can delete your account directly in the app, whenever you like. REFUND RADAR PRO Pro unlocks: • Unlimited entries — the free plan stops at 25 • Connect Gmail and Outlook directly • Forwarding for iCloud, GMX, web.de, Yahoo and other providers • AI reads deadline, merchant and amount from your receipts • Escalating reminders and priority alerts • Track refunds through to the credit note Plans: • Pro monthly — renews every month • Pro yearly — renews every year The price for your region is shown in the App Store before you confirm. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Billing runs through your Apple account, where you can manage and cancel it at any time.

Verdict
The clearest difference is in-app purchases: flateXSecure at none against Refund Radar's 2. flateXSecure also leads on iOS requirement (12.0 vs 17.0). Refund Radar's advantage is update cadence (daily vs every 5 months). On price, ads and device support there is nothing between them.
